Minnesota-based Prime Therapeutics said Tuesday it will be adding 200 customer service jobs to its Irving location.

The pharmacy benefit manager already has more than 600 employees working at the Irving center and is seeking to fill the new positions immediately. Start dates range from Aug. 5 through Oct. 7, according to a company statement.

“Irving has been, and continues to be, an excellent market for the skill set we need to deliver a superior experience for our members,” Prime’s chief operating officer, Glen Laschober, said in a statement.

The new hires will handle calls from members, assisting them with benefit plans and claim processing.
